Answer:

see explanation

Step-by-step explanation:

Given

s(t) = 10t²

To find s(2) and s(5) substitute t = 2 and t = 5 into f(t)

(a)

s(2) = 10 × 2² = 10 × 4 = 40

s(5) = 10 × 5² = 10 × 25 = 250

(b)

s(5) - s(2) = 250 - 40 = 210

This represents the distance travelled in 3 hours

(c)

The average rate of change is measured as

\frac{s(5)-s(2)}{5-2}

= \frac{250-40}{3}

= \frac{210}{3}

= 70 miles per hour

5 . x^2 /x^2 for x=2
goblinko [34]

Answer:

1

Step-by-step explanation:

Hello!

Plug in 2 for x and simplify.

<h3>Evaluate</h3>
  • \frac{x^2}{x^2}
  • \frac{2^2}{2^2}
  • \frac44
  • 1

We could have also simplified the fraction first. If a fraction has the same number in the numerator and the denominator, then it is always equal to 1, no matter what values of x.
